The

bearing plates '14:, 15 thus have their outer of the flange 13.

edges turned away :trom'each' other, and this is al s7o the case withthe bearing plates 16,1 I

In order to secure a wire in the hole 18 the operator grasps the bearingplatel and raises it, therebycompressing the spring 20. The wire is nextinserted through the hole 18 and the bearing plates released so that thepressure of the spring forces the bear-' ing plate 14 directly downwardupon the wire, pinning it against the upper surface Other wires 20, 21,22, 23 may be connected with the binding post. In order to connect thewires 20, 21, they are simply forced in between the clamping plates 14,15, as will be understood. from Figs. 1, 2 and Similarly the wires 22,23 are clamped intermediate the clamping plates 16, 17. 1, wires 24, mayalso be connected, the wire 24 being inserted through the hole 18, andthe wire 25 through the hole 19, in each case the wire being held bypressure upon the adjacent clamping plate 14 or 17 as the "case may be.

Integralwith thestem 10 is a threaded portion 26 which screws into thesleeve 8, as will be understood from Fig. 2, and is provided with a hole27. The. purpose of this hole can best be understood by reference toFig. 5, which shows aslightly different form of base. In this instancethe stem is shown at 10 and differs not at all from the stem 10appearing in Figs. 2, 3 and 4, except in the fact that its upper end hasnot yet been spun. The lower end of the stem l0 'is provided with athreaded portion 26, or, in other words, is identical withthecorresponding portion shown in Fig. 2 and has a hole 27 extendingdiametrically through it. The threaded portion 26 of the stem 10 extendsthrough a plate 28 of electrosc. Engaging the lower end of the threadedportion 26 are revoluble nuts 29,

3O threaded internally and applied as indicated in Fig. 5. The hole 27and the nut 30 may be employed for clamping an additional wire inposition. For this purpose the wire is extended through the hole and thenut 30 is run down upon it.

In the construction shown in Fig. 6 the stem 31 is provided at itsbottom with a flange 32 and is mounted upon an anchorage 33 which isembedded in a base 34 of insulating material. The anchorage 33isprovided with a hole 35 extending through it and adapted to receive asmaller portion of the insulating material. A vertically disposedpartition 36 is sometimes used as indicated in Fig. 7. The stem 38 isprovided with an elongated portion 39 having a flange 10 integral withit and revolubly en- As indicated by Figs. 3 and' I gaging this flangeis a nut 41. i The stem 38 is provided with a flange 42 integral withit. I

In order to assemble the inv Fi tended through the partition 36 and thenut all is fitted upon the flange 10 and is tightened against thepartition 36. This construction affords a double-ended binding partsindicated post which, in other respects, is similar to those shown inthe other fi res.

I do not limit myself to the use of any particular metal or of anyparticular insulating material in the construction of thevariouspartsiof this binding post and parts associated-with it. Neitherdo I limit my 7, the elongated portion 39 18 ex-:

self to th'e xact form of binding post shown in the *drawings.

Having thus described my invention,"I

claim as new and desire to secure by Letters Patent 1. A binding post,comprising a stem,

clamping plates encircling the same, means for preventing the easyremoval of said,

clamping plates from said stem, and a spring for pressing said clampingplates apart in the general direction of said stem.

2. A binding post, comprising a body portion provided with a flange, andfurther'provided with a portion for connecting said body portion with abase, said stem being Further provided at its end opposite said flangewith another flange, clamping plates disposed intermediate said flanges,and a spring member disposedintermediate said clamping plates. 4

3. A binding post, comprising a pair of movable clamping plates havingtheir edges cupped in opposite directions to facilitate the entrance ofa wire intermediate said clamping plates, and means for pressing one ofsaid clamping plates toward the other.

4. A binding post, comprising a pair of .movable clamping plates, a stemthreaded through said clamping plates, and a spring disposedintermediate said clamping plates for forcing the same in oppositedirections.

5. A binding post, comprising a stem provided with a flange, a movableclampin plate encircling said stem and disposed ad jacent to said flangewhich forms a limiting stop therefor, a second movable: clamping plate,and means for forcing-said second clamping plate toward saidfirst-mentioned clamping plate by spring tension.

(1. A binding Lpost, comprising a body member, a plurality of clampingplates of annular form. arranged in pairs and encircling said bodymember, and a s ring engaging two of said ,clampin p ates and forcingthe same in opposite cfirections. I

.7. A binding post, comprising a stem, and a pair of movable clam mgplates mounted thereupon and adapte 'to receive a wire therebetwee i,said ciampiog cupped in opposite directions the entrance of said wire tobe clamped.

S. The combimition of a stem, :1 pair of movable clampingplates mountedthereupon and adapted to secure a wire, another pair of movableolan'iping piates mounted upon said stem and adapted to secure anotherwire, anda spring disposed into ediate said pairs of clamping plates andcompressing the same in opposite directions.

9. A binding post, compr' ling stein pro vided with an annular tiangespun oufwardly therefrom and integral tnerewith, and clamping, membersslidabl mounted upon said stem, one of said clamping members being mo'able relatively to another for the purpose ot securing a wiretheretait-ween.

10. A binding post comprising;' a body member provided with a portionfor securing it to a support, and further provided with flanges,clan'ipin members eonneoted to said body member and movable in oppositedirectioi'is, and spring mechanism disposed between said clampingmembers for exerting pressure against them.

11. A. binding post, comprising;

a body member provided with a portion for securinnit to a support, andfurther provided with hinges, a pair of movable clamping memberscom'iected to said body member, and means for setanring conductor underspring tension between said pair of said clan'ipingmembe 12. A bindingpost, comprising a body member novided with-a portion for seem ing it toa support, and further provided with a flange, a pair of morableclamping members, and a spring for forcing one of said clampingmemberstoward another.
